Summary
Soft bottom macrobenthic fauna of Porto Santo Island is poorly documented, nevertheless following the "Preliminary Assessment of the Effects of the Aragon oil spill in Porto Santo Island" during an intensive survey on ~a.~ 1991, several \ndata were recorded on upper level surface sediments, both intertidal and subtidal (from 0 to -20m) as well as its faunal composition. All the analysed soft bottom substrate's samples can be classified as sands, varying from medium to fine sands. The macrobenthic fauna is clearly dominated by three taxonomic groups: polychaetes, bivalves and amphipods. \nPolychaetes are the dominant group on intertidal zones while bivalves dominate at the deepest level prospected (-20m), between these extreme levels amphipods are the major group at least at - 10m, while at -5m there is no clear group dominance and gastropods and tanaids are present. Cluster analysis on the global matrix of sediment parameters and \ntaxonomic data came out with two major groups of stations, the first including the finest sands, and the second one grouping stations with the coarser sediments. Evidence of the oil spill impact is mainly assessed by values concerning the microphytobenthos and the macrozoobenthic community dominance and specific diversity.
